Abstract本发明涉及一种基于IEC60870-5-104远动规约的PLC通信模块,包括规约逻辑控制器通过以太网端口与IEC60870-5-104远动规约主站连接,通过socket通信技术进行通信,接收到IEC60870-5-104远动规约主站数据指令后进行解析;规约逻辑控制器连接模块数据存储区,将解析后的数据存储到模块数据存储区;数据镜像连接模块数据存储区,将模块数据存储区中的数据与PLC控制器中的缓冲区进行数据通信。本发明用于对工业现场,尤其是设备分布较广的工业现场数据的采集、处理和控制,系统独立、通讯稳定、互操作性强、可靠性高。
Other AbstractThe invention relates to a PLC (programmable logic controller) communication module based on the IEC (international electrotechnical commission) 60870-5-104 telecontrol protocol. The PLC communication module is characterized in that a protocol logic controller is connected with an IEC60870-5-104 telecontrol protocol master station through an Ethernet port, performs communication by means of a socket communication technology and performs analysis after receiving a data instruction from the IEC60870-5-104 telecontrol protocol master station; the protocol logic controller is connected with a module data storage area and stores analyzed data to the module data storage area; a data mirror is connected with the module data storage area and enables data in the module data storage area to have data communication with a buffer area in a PLC controller. The PLC communication module is used for data acquisition, processing and control of industrial scenes, especially industrial scenes with widely distributed equipment, the system is independent, the communication is stable, and the interoperability and the reliability are high.
